Chelsea Technologies Group (CTG) provides multi parameter water sensor for the environmental monitoring (both oceanographic and inland water), contamination monitoring and process control markets. Satisfying the needs of both the civil and military markets CTG specialises in technologies ranging from optical and acoustic sensors to comprehensive environmental and process monitoring systems. For monitoring of algae loading at abstraction points to Water Treatment Works (to protect and maximize longevity of filters used within the works): In situ fluorometers UniLux, Trilux algae monitor would be suitable. For protection of water supplies against accidental or deliberate contamination: FastGuard Water contamination detection system and UviLux Hydrocarbon fluorometer would be ideal. For detection of effluent levels, Biological Oxygen Demand (BOD) tracking, Combined Sewage Overflow / fish kill events and Grey Water / Black Water cross-over: UviLux Effluent Monitor

A team of engineers and scientists are engaged in the design and manufacture of a range of sensors and systems for the marine, environmental, defence, homeland security, industrial process control and life science markets.

For over 50 years, customers have been using our high quality sensors and systems in a wide range of applications - submariners are using them to understand the environment they pass through, water authorities are using them to test water supplies to guard against chemical attack by terrorists. Scientists are using our sensors to monitor oceanic algae to tackle climate change and shipping companies have installed state of the art in-line sensors to monitor their exhaust gas cleaning systems and ballast water in order to prevent contamination of seas. Oil companies are using our sensors to detect subsea pipeline leaks and monitor oil spills. Demand for the Chelsea sensors and systems has also come from the food and automobile industries.
